Patented 27, 1931 UNITED STATES PATENT, OFFICE AUGUST H. LEIPERT, OF COLLEGE POINT, NEW YORK, ASSIGNOB TO INTERNATIONAL MOTOR COMPANY, OF NEW YORK, N. 2., A COlfiPORA'lION OF DELAWARE WHEEL-TORQUE IN SULATOB Application filed June 12,

The present invention relates to torque cushioning devices and embodies, more specifically, an improved form of torque cushioning device which is adapted to be 1nserted between the axle and wheel of a vehlcle.

Devices of a similar nature have been proposed heretofore and contstruct'ed 1D."S l1Ch manner that a new form oflwheel 1s required torque cushioning device which isconstructed in such manner that it may be inserted directly between the axle, or jack shaft, and the hub of a standard wheel, thus forming an accessory which is easily applied to wheels which are now in production and use.

An object of the invention, therefore, is to provide a device for cushioning torque and lessening the starting shock between the axle shaft and wheel.

A further object of the invention is to provide a device of the'abovecharacter which is readily mounted between the wheel hub and jack shaft of the vehicle.

A further bbject of the invention is to provide a structure of the above character which may be applied directly to standard forms of Wheels and afiords a cushioning efiect uponthe torque transmitted between the wheel-hub and jack shaft Further objects of the invention, not specifically enumerated-above, will be apparent as it is described .in greater detail in con- ,nection with the accompanying drawings,

wherein:

Figure 1 is a view in side elevation, partly brokert away and in section, showing one form of the invention; I

Figure 2 is aview in section, taken'on line 22 'of Figure 1, and looking in the direction of the arrows.

Referring 'to the above drawings, a designatesan axle housing carrying a ack shaft (2 having a splined end a. A wheel hub I),

- here shown as carrying a wheel structure v adapted to accommodate a pair of tires 12',

is formed with spokes b and rim b Bolts b are provided to secure brake drum b to the wheel and the construction, thus far, follows a conventional form of wheel now in use. Bearings b mount the wheel hub upon the axle housing a in the usual manner.

To the annular boss 6, formed on the outer face of the huh I), a housing a, is secured. Bolts 0 serve to secure the housing 0 to the wheel hub and also carry an 'apertured sealingdisc d, havinga sealing ring (1'.

A spider e is carried by the splined end a ofthe jack shaft a and is provided with a sealing disc 6, held in place by shoulder 6 The sealing disc e is supported by an inwardly projecting portionf on a cover plate 7 which is secured to housing 0 by means of bolts 7.

Carrier 9' is secured to the spider e at the periphery thereof, and formed with web extensions g, forming seats for cushioning elements to be described. hereinafter. Elongated slots 9 are formed in the carrier 9 to receive bolts 7, the slots being sufliciently elongated to permit a desired degree of moyement between the carrier 9 and bolts 1:

Extending inwardly from the annular'periphery of housing a, are web-shaped seats 0 which cooperate with seats g on the earrier g and alternate with respect. thereto. The inwardlyprojecting reenforcing web 0 is formed between the seats to serve as a re enforcementtherefor and provided with an aperture 0 through which the bolts 7 may pass.

The cover plate is formed with recesses f in which ..the hea s of bolts f are received and suitable cushioning elements it, such as blocks of ielding non-metallic material, are positione between the respective seats 0 and g.

It will be seen that the spider e and carfrom the standard forms of wheels now in use. While the invention has been described with specific reference to the construction shown in the accompanying drawings, it is obvious that changes in design and-arrangement of parts may be made to adapt the invention to use on various forms of Wheels without departing from the scope of 'the invention as defined in the appended claims.

10 I claim as my invention:

1. In-a torque cushioning device adapted to be inserted between an'axle and a wheel hub embodying a housing mounted on the wheel hub and a spider mounted on theaxle,

15 a carrier on the spider and extending within the housing, means to resist relative rotation of the carrier and housing, and a sealing disc on the housing and engagingthe spider to seal the spider and housing from the axle g and wheel hub bearing.

2. In a torque cushioning device adapted to be inserted between anax le and a wheel hub embodying a housing mounted on the Wheel hub and a spider carried by the axle,

2 a carrier on the spider extending within the housing, pairs of inwardly extending V- shaped webs within the housing, pairs of outwardly extending ii-shaped webson the carrier, and blocks of yielding non-metallic 3e material between adjacent Webs of the respective members.

This specification signed this 7th day'of June, A. D. 1929.
